The fire broke out before 2 p.m. at a house in the 24W600 block of Lawrence Avenue in the Keeneyville area of Bloomingdale Township. The sister of a survivor said a space heater might have sparked the fast-moving blaze, although the official cause has not been determined.

Killed in the blaze were Steven Elliot, 32, and Lori Ann Breese, 37, both residents of the house. Cesar Euan, another resident of the house, and Edith Hernandez of Bolingbrook were injured, along with an 11-year-old girl and a 5-year-old boy, the sheriff's office said in a statement today. All the injured were taken to Glen Oaks Hospital.
